how do i undo this update? i hate it. i do not like the new gallery formats, too small to see negating point of having a phone with a large screen, battery life has dropped in half and now the largest user is "media" - meaning downloads and such ? im not downloading anything so quit killing my battery!!! i use wifi alot at home and work and now the mobile data is staying on and trying to run at the same time too? i care nothing about "split screens" since its pointless to use with 99% of the apps. i want to undo this crappy "update" that has set my phone back to a lesser device i am not happy with. Up til this update i loved my phone. why force things on us we dont want, wont use, bog phone down, kill the battery life, and ruin the plus side of a phone this big?
